Can someone please help!
I am having issues with my signal.
It is much weaker than my previous blackberries (9000, 9700, 9780, 9800)
The blackberry while in call keeps switching from EDGE to edge or to GSM and then switches back to big letters. Sometimes, while driving, it gets stuck in GSM and i have to reset connections to get the data back up. I am currently running 7.0.0.440 and tried all other previous updates before... all had the same problem.
Is anyone experiencing a similar issue?

have u verified that other BB models are not behaving the same way at the locations you have experienced this?

maybe u should try another device to verify that the problem is a 9900 problem

Yes I have verified this. It is not happening to other phones on my network. Checked my friends' blackberries

can anyone help? could i be possibly using the wrong frequency/mhz phone on my network? I am in Russia on the Beeline network. All previous blackberries didnt have a problem. I had a 9700 t-mobile version and a 9800 att version
