Paul from Smartphone forum MoDaCo.com has been playing around with the various “flavours” of OS for the SPV e200 (aka the QTek 8080 / xPhone).
He’s found a few very interesting differences. Firstly, when compared to the Orange SPV e200 build, the QTek 8080 OS appears to have far superior battery life. Secondly, and strangely, the T9 “losing new words after the phone has been rebooted” but has been fixed in the QTek and xPhone versions. This bug still appears on the e200 from Orange, although in theory it should be resolved.
