This thread is a little stale, but I thought I'd see if anyone has tried the new LG CU575 with their NXXX yet.. The phone has 3.6 hspda, compared to the CU500 which had 1.8.. Both of these phones are selling on ebay for very very cheap.. in the range of $110 - $140. Seems like a cheap way to get on the 3.5G bandwagon, though. :-)
