The I-mate JAM Black is the same device that would also be known as Qtek S110 since both have been produced by HTC. No prizes for guessing the rich color of this phone - its black obviously. The device is more likely to be called as a PDA rather than a phone thanks to its form factor as well as high end features.

Review

I have been using this phone from past 10 months, this is an excellent phone, with only wifi facility missing which can be covered with sandisk combo card.
Go for it, its the best phone ever made ;)
