Just opened a ticket to return mine within the 14 days no questions asked thing they do. Very disappointed I ordered one for my birthday when they started the Tuesday no invite deal. I only used it for a day but had the following problems;
3 in touch app wouldn't work as it said the phone was rooted even though it wasn't the workarounds I used on my rooted S3 didn't work and I really need that app as there is no signal where I work..
Just an FYi, according to the play store the latest version of this app now works on rooted devices
Sorry to hear you had a poor experience, hope you get your refund sorted smoothly.
