of course.. jailbreak is the only way to go. and op asked for iphone apps, so i gave her a few of the most useful ones... seriously, i have yet to need the appstore after jailbreaking.. all the usefully packets are third party and whilst it takes a friggin long while to download packets and load I think Cydia is a decent packet injector ...i use it more than Icy that's for sure
but it's good to install icy as well because my cydia got messed up because my phone crashed when i was using it and my mac address was spoofed .. so i deleted the selection.plist file via terminal and reinstalled via Icy
handy in a tight spot
