Technophone seeks upgrade advice please

Maidenover

Hi everyone
I need help...in more ways than one ..........but for now can anyone with good knowledge of todays latest mobile phones please help me.

I have had a mobile phone of one sort or another since they were the size of house bricks and have stayed loyal to same provider - now called o2 (can't remember who they were before that).

I have always managed in past to get on with new phones but the latest touch screen phones have got me perplexed. I have visited the o2 store in Bluewater and they all look so cheap and tacky (in my price range). Perhaps I should be honest and tell you at this point that I only pay £10 per month and get unlimited texts and 100 mins calls for this. It suits me fine. I use texts all the time and need a nice phone to hold to do this. I text really quick using left hand thumb only and rarely use phone for calls.

The touch screen ones seem to jump all over the place and not as nice to hold as my present phone (Nokia 6300). Should I stick to my present phone and not bother trying to keep up with new range of phones given my limited needs?

I would quite like the free Sat nav offered on some but I could live without it.

Any thoughts/advice much appreciated.
Cheers.
