Does it make sense that an application would suddenly cause connectivity issues? Not sure if this is a coincidence or related. I am also wondering if I have too many apps on my device. Could not enough memory cause connectivity issues?

Thanks for your help!

Normally applications do not cause connectivity issues.

agreed with DC/DC. i had some connectivity issues in the past on different devices, in most cases it was caused by (in order of frequency)

- bad 3G reception: try to switch to "2G only"
- carrier issues
- RIM network issues
- roaming issues

I'll add seasonal disturbances. At least in my limited experiences reception is significantly reduced in fringe areas during hot humid weather. In my home I'm typically on 1 or 2 bars and some spots no signal but can always find the spot where I will get reception. Each year during late July and August when the weather here is at it's hottest and humidist it gets worse. Right now if I'm in my house I might as well be in a lead lined box. Zero signal at any location in the house and very limited within several blocks.

Anyone else experience this?

You are absolutly correct. Those kinds of conditions can cause problems. A cellphone radio link is probably one of the most difficult radio links to engineer to work well. One side is low power, near the ground and in an essentially random unprepaired site. Just about any problem that has ever befallen a radio link will, at some point, happen to a cellphone link. You can get daily, seasonal, weather related changes. You can also get long term changes as building go up, or trees grow where before there was empty space.

Most of the liturature produce on radio propagation over the past 20 years or so has been on cellphone or satellite to small user terminal (satphone, dish TV, etc) links because there is so much money at stake, and there is so little the companies can do with the hand held side of the radio link.
