What is the best local SIM card in Egypt?

I’m moving to Cairo in the coming days. I own a blackberry Storm, which i just recently unlocked for foreign SIM use. I would love to get data service in Egypt, however I’m sure it will not be easy to accomplish cheaply. So I’m wondering what brands I should look into when i get over there. I would like it to work in Cairo, Lux, and Alex.

Follow up question: Not sure if i should post another ‘thread’ about this but i was wondering since I’ll be gone for four months if i should suspend my Verizon number (which is attached to a family plan still), and if there is any disadvantages to doing so.

Thanks
