Fring

store   is a great mobile client for android, supports ICQ (chat) Skype (calls), Twitter (chat), SIP (phone calls), AIM (chat), MSN Messenger, Google Talk, Yahoo (chat). One of the first apps that supports front camera. The developers have updated the messenger, so now he's got the support of video calls, including using the front camera. The program is very popular and is gaining her fans at a frantic pace. What I would like to note is the need for registration on fring.com (Russian language is supported), takes the contacts from the address book on the phone.
