First, like I said in the subject, I'm new for this things,
Second my natural language isn't English, so there might be lots of grammar faults in this message, sorry for both...

I want to ask that what is the benefits of newer fw versions? For example what is the diffrence between C45 v0.6 and v33 or v50?

Is there any new menus or games or for example a composer in the new versions?

What can I do with a data cable for a c45 except upd. fw. or conn. int. ?

Can I upload or download contact inf. from the phone or sync. them between outlook?

Can I change the visual style of menus (font or animations) ?

Can I change the operator logo or bitmaps for groups?

If I can do this operations, which software that I need and where can I find it?

I now, these questions are very stupid for Pro's (like you ) but I really want to learn...

Thnx
