Well, it looks like there's some good news and some bad news for those holding out for a Samsung Galaxy S II. GSM Arena is reporting that Samsung has decided to upgrade the phone's dual-core processor from 1GHz to 1.2GHz, something that was first revealed on Samsung Estonia's Facebook page and has apparently be confirmed by GSM Arena itself from an "internal source." The bad news is that it seems you'll also have to deal with a bit of a delay. Some UK retailers are now listing a release date of May 6th, while Samsung India has tweeted that the phone's global launch has been delayed by "at least" a month, and that it won't roll out before June.
P.S. There's no indication as to how this upgrade will affect the Tegra 2 version of the phone, which was confirmed to be on track last month.
