Ok. I've been using the iPaq 6315 for a while and while I like the versatility of it, I was constantly annoyed by the BT problem and the multiple resets I have to do daily to keep this thing running. I was ready to give up till Eric (gryph0n) pointed me to the unofficial iPaq ROM that's floating around. Read the description and took the plunge (what the ^*&&) and it's been working great since. Not a single reset due to BT problems. Lost BT connection to my headset maybe once or twice but overall it's been very reliable. Impressive! You can find out plenty of information off here:iPaq ROM
They even have a Newest ROM which flashes the iPaq and restore every tmobile app you used to have. I installed the New ROM, btw, and didn't restore the tmobile stuff myself.
As with any ROM upgrade, your iPaq will be wiped clean (so backup to storage card or PC) and there's always the risk of something not working. This has been tested quite thoroughly so chances are slim but you never know. (enough warning?
) SO, if you are happy with your iPaq, don't have to do it!
Feel free to share comments and ask questions about the ROM here. This gives my iPaq at least another 6 months of usable life. Have fun.
