I didn't have long to play with it, but I must say I'm impressed. Lovely screen, smooth interface, all very nice. But there were a few things I/he wanted to change and I couldn't see if they could be:
Ringtone - There doesn't seem to be the option you sometimes find to change between "ring & vibrate" "vibrate then ring". At the moment, it vibrates for a few seconds and then the ringtone starts.. he wants the noise to start as soon as someone rings! A small thing, perhaps, but I'm sure that was something I used to be able to change on my old win phones.
Keypad - Is qwerty the only option? With meaty fingers and, he'd prefer an old school keypad with t9 input, like you can with android.
Shortcuts - Can you set up shortcuts from the main screen for things like airplane mode, turn data on and off, wireless on/off, etc... or is this something that an app might be able to do for him?
Profiles - I couldn't see anywhere to set up profiles? Feel free to tell me I'm being stupid!
That should do to start, and hopefully I'll get chance to play with it some more soon!
