I brought this phone as a upgrade to an old O2 phone what a mistake. The phone is very good, nice looking with good features and very easy to use. The battery life is poor with the slim battery and only slightly better with the large longlife battery, the software to transfer from PC is a royal pain and conflics with most USB ADSL modems. The main problem however is with 3 themselves, they are a joke, customer service haha forget it you get no joy whatsoever. DON'T USE 3 MOBILE YOU WILL COME TO REGRET IT.
