I need my epic fully functional for at least 20 days with gps working and pretty much everything for an upcoming trip.. I tried syndicate rom and ace rom, they look cool, syndicate rom is very fast but to be honest it wasnt that stable. The 1.0.1 version gave me a very bad bug in which it automaticaly deleted any new files I transfered onto the SD card and the newer version 1.0.2 started force closing everything on me, couldnt even send SMS messages.
I came to the conclussion that eclair was going to be the best option for my situation.. at least we know it's stable. So finding out about this new Froyo version was like light from heaven. I think I am not gona install any custom mods for a while and try the new stock froyo as it is. A big concern is allways battery life, which completly sucked donkeys in eclair but I use this
Amazon.com: Samsung Epic 4G (2800 mAh) Extended Life Battery with Replacement Back Cover: Cell Phones & Accessories
that pretty much ended my battery life problem
