Shimon (he did the coding on this app) just released version 1.20 of aTAKEphONE, with support for OS 2.1
aTAKEphONE will change the way you use your phone to make calls – no more having to open the G1 keyboard to search for contacts, or fiddling with the tiny on-screen keyboard buttons, fast & easy access to all your favorites, call-log and even a dial-by-photo feature !
