I hope that so. Actually, Sharp's model is quite popular in UK due to having David Beckham as a presenter for Vodafone(Sharp is exclusive only Vodafone). The newest TV ads that I've seen is about Beckham sending MMS(picture from GX20) from Spain to England to show a sunny day there that more lovely than raining almost everyday in UK.
p.s. In UK, I'm gonna die of freezing now. I hate minus temperature
This is the cheapest site selling GX22 that I've ever seen around 23,000 baht. That's not mean there are no other places that sell in cheaper price. But I didn't spend time to search actually. http://www.mobilefly.com/product.php?productid=290
I don't think you can find any GX22 in 16,000 baht anyway since even GX20 when it's first launched it has a same price as SE P800 at that time. Btw, hope that Thai operator will have policy to subsidize handset price like other contries abroad so we can buy cheaper mobile phone.
