okay. so from what i have inferred, basically, the a600 and a620(VGA1000) have essentially the same programming software. but, when i try and use this phone with BitPim, (under A620, due to no A600 selection) and try to transfer ringtones and pictures (wallpaper, album), the phone automatically reboots, then shuts down after the sprint screen. on the error log, it displays that the phone becomes idle after switching to "brew mode". any help???
