I am using a 3GS with a tmobile prepaid sim. I was on 4.3.3 with the ipad bb and never had any problems. in December I went up to 6.0.1 using redsn0w_mac_0.9.15b3 and selected preserve ipad bb. (I've never cared about not having GPS functionality.)

Since then, I frequently lose signal and get the "Searching ..." message before it reconnects. When this happens, I lose cell (I don't have data), wifi and sometimes bluetooth.

Any ideas? Should I downgrade bb?

Also, is it worth going up to 6.1.2 while I'm messing around with this?
