Hi Mirolg, thank for your contribution to the TG01 community. I'm very happy with this Tango 8773 WP7 rom even with a little bug for camera, sms and etc, but it still worth for upgrade to WP7 OS. Battery Problem never bother me, just buy few batters for back-up due to small capacity 1000mAh.
One more thing, is it possible to put INTERNET SHARING on this custom rom? like Nokia Lumia 610, quite similar spec (800MHz processor and 256m ram) compare with TG01.
