Sign up with GoogleHi all. I just need some feedback if possible. Our company has just imported a new GSM handset called the Sonim XP1 which will be used in conjunction with Push to Talk or you can use it as a normal cell phone. If you have time please go to the website www.sonimtech.com and have a look at the phone and give me your views or opinions on the handset or the concept of Push to Talk. Your feedback would be invaluable. Thanks
