lately after installing ios4.2 the battery on my 2g ipod touch Has been dieing on 3d games in 30 min. Is that normel? And it takes 1-7 mins to turn on from sleep mode.
If you restored from backup after loading iOS4.1 (I presume it is 4.1 as 4.2 is not out yet), if so do a restore and this time set it up as a new device.
