Things are still heating up for a white iPhone 4 release here in the US. Just in the past week or so we have seen an appearance in an internal Verizon inventory system, a rumored release date of April 26th and now an appearance with Best Buy. Of course, there is a bit of a discrepancy with the release date as Best Buy has it showing as April 27th. But that said, according to Best Buy, the white iPhone 4 will be available in the GSM variety (AT&T). But we suppose that a CDMA Verizon version could arrive on the 26th and a GSM AT&T version on the 27th. Either way, it looks like those who have been waiting for the unicorn like white iPhone 4 are finally going to be able to part with their money. Well, that is assuming they had not given up a long time ago and just went with the black iPhone 4.
