Re: Sprint and Best buy increased price ??!
Go on Craigs List, buy one for $150, put insurance on it to be sure its okay, then you can drop.
Save your upgrade for LTE - I have 5 phones, all expiring next summer, and my last premier upgrade
by the end of June. I'm buying nothing on contract/upgrades/whatever that is 4G. I'm sick of paying for it, we don't have it, won't have it, and now all our phones won't work on LTE whenever it comes out.
So I am upgrading my last 2 to Nexus S 4g and will be happy and wait till the next one comes out.
Do the same, buy right and you can sell right until then, whenever and whatever then is.
