Yes but make sure that whatever software you are using that it has hacked that updated before you do it

MMS (picture, sound and video messaging) is currently (March 2008) unsupported on the iPhone, although the capability is there and could (in theory) be introduced in a later software upgrade.
Sorry but no, if your on PAY AS YOU GO there is no way you can upgrade. Only the plan users may upgrade.
Yes, all iPhone and iPod Touch models use the same operating system, meaning the same software updates.

You may think it is worth the upgrade to an iPhone if you have an Xperia z; many people like the iPhones.
it is important to upgrade software because it makes it harder for glitches and fires to get in to that software.
most of the improvements (speed, new apps, fixing bugs, etc.) are just software changes, so your old iphone 3g is basically the same as the 3gs with the free software upgrade, the only real difference being that the new iphone 3gs has a built in video cam function. so, final answer, it is worth it if you do not have an iphone already (although the at&t service is a bit pricey) if you have an iphone already, just get the upgrade. (and if you really need a pocket cam/video recorder, just buy a flip cam for like $99) IMPROVEMENT: if you want to record video on your original iPhone or iPhone 3G, there's an app for that!
