Coming up on my upgrade and I'm looking at either the g3 or g4, obviously they're both huge upgrades over my pantech perception which died a few months ago and I've been using a pay as you go tracfone in the interim. Best buy has a promo going on where I can get the g3 for free with a $100 gift card or the g4 for 199 with the same gc offer. Just curious what others would do in the same situation, thank you.
