Despite the release date being a few days away on the 22nd of October, some customers have already received their G1, the new smartphone from T-Mobile and competitor to the Sony Ericsson Xperia X1 smartphone.

Some pre-existing T-Mobile customers that were lucky enough to pre order a G1, manufactured by HTC, have had their new phones shipped out to them in advance of the official release date, leaving customers that weren’t already T-Mobile users a little ‘miffed’, according to Engadget.

Expect a plethora of pictures and videos of the G1 to arrive on the internet at any time.

Jouwmobiel have posted up not only a review of the Sony Ericsson Xperia X1 but also an in depth comparison of the X1 and the T-Mobile G1 with plenty of photos and videos included. The site is a Dutch site so no English but, it’s worth translating and a link to a translated version of the X1 vs G1 article is below.

Seems the X1 is, unsurprisingly the better looking and better designed phone of the two models and it’s smaller too. The build quality of the X1 impressed the reviewer in comparison to that of the G1. In fact most aspects of the X1 are praised more than the features of the G1. It’s certainly a positive comparison/review for Sony Ericsson.
