The Upstage is a great concept phone. Full of nice features for that all-in-one feel. The phone comes complete with an extended battery that is slyly hidden inside the nice pleather case that is included with the phone. As far as looks and concept go this phone is a great looker and will keep people flipping it over and like those "how to keep a stupid person busy" keychains.
However when it comes down to the most important part of the phone, the actual performance, there are many flaws that I will detail for you. I have owned this phone for almost a year now and it is the biggest mistake I have ever made. First and foremost if you get into one of those weird oh i missed this persons call so i'm gonna call them back and you put the phone up to your ear and it starts vibrating in your hand cause they just called you at the same time as well... (i hope you understand what i'm trying to say) the phone will lock up, and you'll be unable to turn it off, answer the call, ignore the call or do anything until the call has gone to voicemail.
The flip side of the phone with the touch buttons is absolutely the most horrible thing i have ever had to deal with on a cell phone. The touchpad is far far too sensitive and the "back" button is just below the --> button so you try to navigate to the right and oh you're back a menu, same for the left except that one is the end key. You can only read texts once on the front, but after you've ended it you have to flip the damn thing over and go through the menu to get to it again.
Overall this phone is terrible. I could go on all day about it. It is definitely a stylish phone and will again, keep people occupied for a while, but you'll be more annoyed with the stupid thing than its worth.
