It's called Fring Currently you can't search for it but if you go to the Itunes appstore (not the mobile one) and go to Social Network and it should be the most recent release. You can use it with AIM, Yahoo, Gtalk, Skype, AIM, Twitter, and ICQ It's also free! http://phobos.apple.com/WebObjects/MZStore.woa/wa/viewSoftware?id=290948830&mt=8
You can now find it in the U.S. AppStore on the iPhone. Just go into the "Social Networking" Category, and it's the first app at the top of the list. It's still not listed if you use the Search feature in the AppStore on the iPhone, but I assume that it will be there sooner or later. Enjoy!
Yeah, that too! haha. Seems like I can't trust the spellcheck on my phone anymore =/ And of course I can't edit the title Fring isn't bad but it isn't without fault either. There are a few issues with logging in but that could be due to the number of people using it. You can only chat with people on your buddylist and you can't add anyone unless they have a fring account. I also haven't been able to connect to friends on ichat. It's a good start and I can't wait for the updates
Ugh very dissapointing... Fring was awesome on jailbreak but I hate it now... It sucks.... I recommend beejive! Skype and stuff is on their roadmap and they are planning on adding it!
