"As someone who doesn't reside in the USA, I was wondering what would be the best way to get internet for my computer in the US for a couple of weeks? If it were Europe I know I'd look for some prepaid data. Is there anything similar offered by American carriers? A MiFi or a data SIM that I can tether from would work, but I'm trying to maintain a tight budget. Help!"
Make sure I understand this in regards to Cable providers, I have 3 TV's non Digital with Cable connected direct for basic and extended package. These TVs will need some sort of converter from my Cable provider February 2009?
If you have cable you will NOT need any converter.
