New Phone Upsides and Downsides

After getting back from Shinjuku (client), I've been assigned into a new project to which the program coding is only limited to 1 whole week (8 days to be exact). Right now I've been crash coursing on the program so I would be able to finish it on time. I was able to change my phone last Sunday from the old Toshiba phone to the new Sony Ericsson which I'm currently using. Problem with changing phone units, is that you have to allocate some time to learn the features and functions of the new phone, especially since both phones are from 2 different companies. Well I wanted to buy change my old phone to the Sharp 902SH model but I still find that model expensive. It's currently at 17K yen or around 8.5-9K pesos. I'll wait for the price to go lower than 10K yen before I change my phone again. And by that time I'll sell my phone to my brother :P (evil me). I got my current phone at 6K yen or 3K pesos and the good and bad thing with it is that since it is a 3G phone you can use a sim card with it. Good, because I can use it in the Philippines. Bad, because it can be stolen and used by other people. The only thing that I can do to frustrate the person who might steal it is set its language into Japanese only then let them figure out how it works. Once I'm able to buy the Sharp 902SH phone, then it would be a lot safer since there are no Sharp phones in the Philippines at least they would have a bit of a hard time finding support for it. Beyond that the only problem that I'm facing is I don't have time to study my phone's features, functions and programs. Since I'm facing a very tight schedule and other priorities. Hopefully I'll have time to fix my schedule up after this week.
