"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!"
My partner has the Samsung Wave, and it is not bad at all. Not many samsung apps or widgets but there's room to grow. Fast ui, good keyboard and a decent camera with art filter styles means she is happy. One thing it does that she loves is displays the SMS messages as conversations.
