I installed AIM from BlackBerry's web site but I cannot login. I get the error message: "Device has been denied access by the server."
Note that I can login to this service from my 9700 using the same SIM card but not from my new 9900 I bought as an upgrade. Is this application not compatible with OS 7.0? Note that it is not available in App World for the 9900 while it is available on the store for the 9700.
Correct, it is, strangely enough... not compatible with OS7 right now. I rec'd an error message to this effect when trying to download via the usual blackberry aim d/l link.
We saw this same kind of incompatibility when OS 5 was first released, and then again with OS 6. OS 7 is still too new for complete compatibility, but after a month or so they should be well on the way to ironing out these things.
The onus to make apps compatible is on the app developers themselves. With BlackBerry dropping off in market share I would't be surprised to see solving these compatibility issues take a back seat to other platforms like iOS and Android. But it will happen. You just have to be patient.
