help me get a good new mobile phone...

Well you have to ask yourself what you want. What features would work best, what you don't need. Those things are important to consider, because the smarter the phone. And, if you have a contract, are you ready to lock yourself into another? If not, do you want to go under contract? Most phones require at least a 2-year contract. If you liked your privious phone, think about what you liked best about it. If that's the case, stick with that brand. Only switch to something else if you found more cons about your previous phone then pros.
