Pls who is using, have used and came across d phone above. Does it worth it as a smart phone? Pls what are d disadvantages? These is a phone I will be using in my work place as a field Engineer. I will be reporting every thing I did in the field via the phone, all emails sent between me and my company will be on the phone. Every uploading and downloading, cameras will come via the phone. Does the battery worth it? Thanks
