I am waiting for my visa to come, so that I can be in Tripoli. I have gathered some information (obviously with the help of Expat.com and all of you). Voltage range in Libya is 220-240 V, 50 Hz as in UK and India. For laptop and phone charger it will work just fine.
The two main mobile carriers are Al Madar and Libyana. I only have a gsm phone so I can't verify CDMA support. In Tripoli, I've found coverage to be quite good. Al Madar supports edge data and libyana has 3g. I mostly use skype for international calls.
There are no CDMA mobile phone services in Libya. CDMA is available though as a wireless phone service for homes where there are no landlines available.
This service also has a rudimentary internet connection built-in, works at about dialup speed.
