Thanks for the reply Mysertious Stranger. I'm not too sure about the clock speed, never checked anything like that but i'll have a look into it later. Any ideas what would cause a 'CPU / crystal oscillator issue', or how to fix it?
R.E the S730, I should probably have explained it's not really a good enough upgrade for me
beacuse the main feature seems to be 3G data and sadly I don't live in an area where i'll get 3G signal
Personally I still prefer the look of the S710 as well but that's just personal choice. You've got a good point about the processor speed and battery figures but these 2 things aren't really enough for me to justify splashing out on a whole new phone. Also, hasn't the S730 had problem with storage space? This was going back a while so maybe all that's been fixed but I remember hearing a few bad stories about it.
