Well, if you're jailbroken there's no better place than cydia for apps. There are additional sources within cydia you can add which will allow you to see and download even more apps. And then of course there's the app store for errything else.
LOL. What a sneaky spam. Appshopper is pretty much the place to go. The site is easy to use. And they keep on top of changes pretty well. It has great filters. You can filter free from paid... price changes, updates and new apps too. And their feeds are easy to use. Their addresses are easy to type into the feed reader apps. I check the feeds several times a day.
Wow two spammers in one thread. LOL. Might want to wipe the brown off your nose. Haha. Just kidding. We all love EIC. It is my goto place for all of my iPhone news, gossip, instruction, and general discussion... all except for app news.
EIC used to be my first place too until I found www.appshopper.com. I trust a website dedicated to app news a lot more than the desire of people to share apps they think are cool.
