I'm getting my very first Android phone in 3 days. I'm wondering if there are any suggestions out there for any apps that any serious Android device owner MUST HAVE. PS. The phone I'm getting is the HTC EVO, which runs on ANdroid 2.1 (Eclair) with Sense. What top 5 (or top 2, or top 10) apps should be priority #1 to get as soon as I get my device activated? and How much do they cost?
