Question is not quite clear that if you just want to leave this phone or buy new or want to make this one more usable.
As per me, you should buy new phone as your requirements are fairly different now. Now, even mid-range phone give above ability. You have to also say your budget for your next mobile then you can findit easy to select a suitable phone yousrlf.
Also, what is your priority ie. which type of phone like ie. sliding, bar, qwerty , touchscreen etc.
