I am new to the iphone and have succesfully unlocked my Dad's 1st gen phone (hes just upgraded to 3G) with the Dev Team's Pwnage Tool everything seems fine but i just wanted to check a few things. 1) Youtube: I've heard rumours of numerous problems with this. Mine seems to work but it is very slow downloading a video. Is this normal? Any way to speed it up? I am connected to the internet through my home wi-fi so that should not be a problem and safari on the iphone is quick using my home wi-fi. 2) Cydia: Could anyone give a bit more detail on what this? Its uses? If all iphones have it or just unlocked ones? I think it has something to do with downloading 3rd party applications. 3) Applications: Am i able to download any application i want (free or paid for) from the "App Store" or will this be a problem for an unlocked iphone. 4) Notes: Is there any way to sync notes on the iphone with stickies or something similar on my mac? I know you can create a contact as ntoes and just to use that but was wondering if any proper method had been set up? 5) Is there anything in particular i need to be careful about with an unlocked iphone e.g. software updates (itunes/iphone). Cheers for all your help.
