So, I'm interested/considering buying a new cell phone. I want a Blackberry Curve. I'm looking around on ebay[cause my upgrade isn't until october and my enV is SHIT], but what are some tips to make sure that I'm not gonna get conned? I bought an 'ipod' off ebay once and it ended up not being a real ipod. yes, it was my fault for not paying attention more closely but i definitely will this time. halp plz ]:
