The O2 XDA IIi keeps many of the features we liked in the earlier model, while also boosting processing power.

A very good phone in terms of features, but way too large and heavy for most people.

The 8800 is a ridiculously expensive mobile handset for what it offers, but it looks absolutely fantastic. If you like to stand out in the crowd, then this phone is definitely for you.

The O2 is a good option for business consumers who want the convenience of a phone integrated with their PDA.
