I have had an 8700c and am very happy with it. I have not upgraded to the 8800 mainly because it does not have 3G. I feel the same way about the 8300. To me, wifi, even if the 8300 has it, is not of that much utility. I want faster data speeds (for the BB or tethering to my laptop) when Wifi is not available.

Is there any possibility of a BB with 3G anytime soon.

My understanding is it supports Edge.

3G will not come until the 9XXX series of BB's come out late this year that also support HPSDA. HPSDA is the one we all really need so we can do voice and data at the same time.

[NJBlackBerry]

Or even HSPDA....
Rumors, rumors everywhere....

Get in line. There are lots of things that we all want. That will be in the coming years. Only RIM/Blackberry knows.

If by "soon" you mean the next few years, yes.

If, however, you mean the next few months, no.

Considering that all we have is speculation on the release ob the 83XX's it's a bit early to worry about any pending release of the 9XXX's.

and hopefully HSDPA too!

I thought 3G and HSPDA were the same. Shows what I know. Can someone explain the difference?

its HSDPA btw. saying they're the same is akin to saying 802.11g and broadband are the same. they aren't in the same category because HSDPA is a FORM of 3G that allows voice and data to be used at the same time so you can potentially download a file or song or whatever and be on a call at the same time. 3G is just a general term for cellular high speed. UMTS is a slower form of 3G that does not allow voice and data at the same time.

iwas readin reuters tonight apently $G is already in the works
but sprint seems to be the onloy carrier testing it out cures you sprint an the other cdma carriers

[nike30]

Galvatron - are you typing very fast on your phone when you post? Sometimes I can understand what the heck you're trying to say!

A brief history of mobile radio technologies:

"1G" - analog phones; switched access. AMPS.
"2G" - digital phones; switched access. TDMA, GSM, CDMA
"2.5G" - digital phones with packet data (switched voice). 1xRTT, GPRS
"2.75G" - faster data. EDGE, EV-DO
"3G" - simultaneous operation of switched voice and packet data. W-CDMA (UMTS), CDMA2000*
"3.5G" - faster data access. HSDPA, HSUPA, EV-DO RevA, EV-DO revB
"4G" - packet voice and data. SC-TDMA; IMS/VCC

I thought CDMA2000, at least on THIS continent preceeded EV-DO, even for Verizon first to launch EV-DO. Oh well.

Can anyone extrapolate these technologies to Theoretical & Real-World Max data transfer rates?

GSM = 9.6-12.6kbps (up & down)
GPRS = 43.6/.8kbps Down (Thoeretical 53kbps)
EDGE = 180kbps Down/26kbps up (NON tethered/ 386kbps Down Theoretical) - this on MSC-9 algorhythm.
anything any body can correct or adjust?

Hence the asterisk. Qualcomm will tell you that all of CDMA is a "3G" network, but that really depends on how you define third-gen.
And yes CDMA2000 predates EV-DO, as well as (i believe) 1xRTT... my timeline doesn't really make as much sense unless you consider CDMA(/2000) to be 2G instead of 3G.

1xRTT was something like 144kbps theoretical,
HSDPA starts at 384kbps and goes upwards... different handsets will give you 720kbps or faster... I'm still not too sure whether this is based on higher modulation rates or multiple concurrent channels
EV-DO rev0 is in the same class as HSDPA, EV-DO revA promises to be faster. There are also updates to EDGE (GERAN) that are meant to increase the data rate of the TDMA based technology, but you won't likely see / hear about that for a few years yet.

When you get into stuff like WiMax and WiFi, then the data speeds really go through the roof. WiMax promises "broadband" speeds wirelessly, by which they mean 1-3Mbps.

All of this becomes fairly redundant if your actual mobile phone can't process the data fast enough... sure you may have peak throughput of 384 kbps, but your average is going to be something closer to half that if your baseband can't run fast enough to decode and "do" something with your data. Even worse is if your fancy apps core can't say, render an image you just downloaded at lightning fast speeds. It all becomes very academic except for those people who want to use their phones as modems for their laptops.

Yay.... like a rocket on the 4th of July...

To Fungineer,
All kidding aside, Thanks for your excellent posts.....

This quote is ridiculous. I have both Cingular HSDPA and Verizon EVDO, and you call EDGE 2.75 and equate it with EVDO? Rlmao!!! Edge is barely faster then 1xrtt. Evdo is just as fast as HSDPA on average. EVDO is definitely 3G, not 2.75. HSDPA will be faster when Cingular allows the faster speeds on their network, but even Cingular doesn't claim average speeds to be more than 400 to 700k, just like EVDO.

We have some 8707V which have 3g built in modem

They don't run on cing. 3g frequency.

I can't wait for a 3g blackberry for the great call quality. My 3g phones sound outstanding. Faster data will rock as well.

[hookem12387]

The best thing about a possible 3g blackberry would be the possibility of slingbox on it.

I was trying to equate that EVDO = 1xRTT++, similar to how EDGE = GPRS++.

But this isn't really the case. Sadly CDMA isn't really my strong point, so I am afraid I was mistaken before.
IS-95 (cdmaOne) is 2G, and 1xRTT is 2.5G
CDMA2000 1xEVDO is 3G, as recognized by IMT, and is much different than 1xRTT - didn't realize that until I did some reading on the weekend.
