Well it was all over the internet that today was supposed to be the release date set for this phone and it's still no where to be found. I checked the website called the 800 number and even called one of the local stores no one had any info on it or knew anything about it. It is on the current rebate form so it must be coming soon.
Don't hold your breath... The phone has been announced since March of last year and was to have been released 3rd quarter of 07. In October I got an email from Sony Ericsson announcing it was available for purchase, yet no one had it. In January there was an "official" Z750 release party in Hollywood with all kinds of celebrities posing for photos, but still no phone. In February it shows up on AT&T rebate forms, which have already expired, but none of the reps I talked to knew anything about it.
Now the much-hyped March 11 date has come and gone... and no phone. On the AT&T forums some customer rep now claims to know that the phone has a March 25 ship date and should be available about a week later. All we can do is wait and see. 🙄
