I'm using Nexus one.
I think you already know about nexus one. Nexus one is one of the android mobile phone developed by Google and HTC. It is not possible to buy nexus one in japan.
I already wrote about japanese 3G signal. Japan has 3 big different phone company. NTT DoCoMo, Softbank mobile (vodaphone), and AU KDDI. DoCoMo and Softbank mobile are using W-CDMA and AU is using CDMA-2000. Many people think that W-CDMA is similar with CDMA-2000. But, it is extension on the GSM. The W-CDMA is little bit different from GSM especially for MMS. The specification of MMS on W-CDMA had little bit different bit from GSM. Android phone cannot access to MMS server by default. So, we needed to compile the android kernel for receiving the MMS on Softbank mobile. Actually, I didn't re-compile the kernel on my phone. Because, it is mobile phone. To re-compiling the kernel for mobile phone has many risks for security and my economy. By such reason, I didn't use MMS on my phone.
2-3 weeks ago, one of my friends who is also using android phone told me that the android market has a application that makes possible to receive not only SMS but also MMS without recompiling the android kernel. It was amazing thing for me. Because, I thought it is impossible to receive the MMS without recompiling the kernel on the W-CDMA. However, I got second time amazing after knowing the mechanism. Softbank mobile made this application independent from the OS. This meaning is that the application has all modules for receiving SMS and MMS, even if the OS has such modules and functionality. It is only my opinion but it is not elegant way to develop the software.
