Last year I bought an INQ 1 on 3 - mostly because of the "free Skype & Instant Messenger for Life" ads. I played with it for a bit, put it somewhere safe and now that it has resurfaced I thought I would see if the "free Skype for life" claim was remotely true.
The phone itself is a nice enough little feature phone with Skype, MSN, and Facebook apps built in. There's no built in twitter client and the built in last.fm client is just a scrobbler (which was disappointing). The Skype client works, but it's a bit limited. You can voice call and IM with other Skype users and if you have Skype credit you can dial out to international numbers - UK phone numbers don't work though. Online Numbers (what Skype In is now called) don't appear to work either. Call quality was good, both Skype to Skype and Skype to Phone.
One interesting thing, I figured that any credit that was on the device would have long expired (it's got to be at least a year since I last used it) but I found that the credit didn't expire. This does mean that I have been unable to put the "free Skype for life" claim though.
