Summary: This phone is factory locked to Boost Mobile and able to work only for Boost network. It is not a unlocked phone (I found it categorized as "unlocked phone"). It wont work on all iDEN (push to talk) network such as NEXTEL worldwide. The lifetime of battery is weak, maybe because it is used.
Summary: In a word, well... I'm probably not allowed to use THAT word in an Amazon review. Do not buy this phone. By everything that is holy, DO NOT BUY THIS PHONE. I bought one when they first came out, and promptly went back to blacberry. It took me years to get over it. Hopefully everyone on the design team is sterile. Hopefully everyone on the marketing team had a quantum personality change, and now use their powers for good, not evil.
Summary: First and foremost this little phone was adored by my 21 year old daughter who is very hard to please. What I did not like was trying to obtain service for it. When I went to Boost Mobile to turn it on, they could not do it because this model is no longer being serviced by Boost Mobile as of June 30, 2013. Amazon.com needs to do further investigation before selling products that have the potential of being returned.
Summary: the i1 should have been released on the iden and cdma network @ the same time because most people knew sprint was going to eventually drop the iden network do to the fact the only people who use it are factory supervisors and construction comp.from a commercial the shown on tv
Summary: I have had this phone since June 2010 and have had no real problems I am really mad that the iden network is being cancelled the phone was really expensive around 350 and after june 2013 will no longer work I will really miss my direct connect my only complaint about this phone is the very short battery life I have to charge it 3times a day.
ebay can not allow the existence of such seller, kill people.

Summary: I like this phone, because it is intelligent, has a walkie-talkie and micro-channel function.However, the seller of goods does not match with the description, unlocked cell phone can not be unlocked, simply to deceive buyers.
