I'm on T-Mobile with my 3 XL, and I check every day still no May update. But the last few updates came out immediately each first Monday, I would check system update, on April 1st, and March 4th and February 4th, and the update was ready to go right away, first try. But now it's back to like before, where updates would be nowhere for a good week or ten days. I'm no Apple iPhone fan, but when there's an update, there's a frigging update for all, doesn't matter if you have Verizon or T-Mobile or unlocked, everyone gets the update the exact same time, same day. I thought Google was finally doing this, but seems to early to celebrate, as they are back to their delays, or maybe it's the carrier, but that never happens when an iPhone has a new update.
