What changes from v3 to v4? Just flashed v3 two days ago, my SDAutoRun didn't work for me, typos typos..who's got the typos...literally...he does... so I don't really wanna go back through the reflash if it's just something small. Course.. if it's something major with all sorts of bugs fixed..that's a different story..
Oye! Reminds me.. Bug located. When switching from UMTS/HSDPA to Edge, for some reason my device battery.dll stopped updating. A soft reset fixed, it was only off by 6%, but it stayed at 81% for like 8 hours. Had me a bit questionable.. Only things that happened that day, besides hitting the UMTS area, were 2 SMS out, 1 SMS in, 1 MMS in, and 2 calls. Device was unused otherwise. Granted, that's not enough to really drain the battery, and I thought "da.., what great battery life now", but the SR told me everything... Probably just a minor thing here or there, hard to reproduce, etc..but ya know.. thought I'd mention it to see if i was known already.
