Yes... you are right. Just noticed that myself. This has happened with them before. Every now and then when they update the site with new phones some current models get left off the update. Happened with the myTouch 4G at one point.
On the other hand their could be a couple of other reasons. One, the on-line store could be out of stock and they pulled the phone until more arrive. Again, this has happened numerous times with T-Mobile.
Secondly, as many of us know, the G2x has had some software issues. I purchased one a few days ago and the software was totally messed up... I returned it to the T-Mobile store where I got it and they gave me a new one that works perfectly. T-Mobile and LG may have been getting a lot of complaints and simply pulled the phone until the software issues are resolved. Or, until Gingerbread was released and took care of issues by default.
The third reason could be that they are getting ready to do a major cost cut on the phone in conjunction with a special promotion and don't want people to buy the phone one day and see it at a much lower price the next.
Bottom line... you just never know!
Not sure if that's the actual reason but quality issues seem to be the cause: Has The G2x Been Pulled From Store Shelves Due To Quality Issues?
I just got the G2x less than a week ago. Mine is flawless. I'm running 2.2.2 as well. No leaks. No bleeds. No crashes. Very curious to read this thread.
That being said, I used to own a BlackBerry Tour. And in that forum, I read from virtually everyone that they had problems. Returned their phones 6 and 7 times. Me, not once. Never had an issue. Same with the Storm. Read about tons of issues. Me, not a problem, ever.
In fact, I have yet to own any phone that ever had a problem, and I've owned tons of phones. If there are problems, I'm sure it's within the realm of normal failure rates. It's simply that those with issues tend to announce them. Those with no issues tend not to say anything at all.
The third reason could be that they are getting ready to do a major cost cut on the phone in conjunction with a special promotion....Bottom line... you just never know!
