My advice: Don't Touch O2 Product.......
I have XDA one giving whole lots of nightmare since new.....and now my hands free spoilt, no one selling the replacement. I contacted the agent they promised to bring it next week (fingers crossed). Now my phone lying idle since I can't use it without hands free, I am driving alot.
Pple always walk into the shop and ask me what are the good phones to buy, i would always ask them what kindof functions are they looking for.
Buying hp is just like buying cameras, just buy something which suits ya requirements and dun be tempted by the 'powerful' functions that it offer because at the end of the day, what's the difference SamSung X430 and a Sony Eric K700i when you don't use the camera (since u r in this forum, i assume u have a much better one), seldom use the radio(if u drive), never need the video recording function or MP3 player and you don't need a TriBand phone as u never intend to travel to US often and blue tooth is not ya cup of tea?
Btw, i'm not saying X430 is not a good phone. My dad owns one and i think it's pretty cool..
