I have a Blackberry Bold with hardware issues (phone shows 4-5 bars of 3G but won't send or receive any data, switches from 3G to EDGE to GPRS to UMA constantly, eating away at my battery) and it needs to be sent in for replacement. Trouble is, I'm running an OS that isn't what my carrier has listed as their latest and if I send it back in without that OS running, they will charge me for the replacement. With JL_cmder, I wipe the handheld completely and with the carrier's OS installed on the computer do I just open Desktop Manager to install the new one?
