Hi everyone , i've been concidering buying a windows mobile phone lately , namely the htc touch pro 2 , and my main concern in multi language input , it doesn't matter what language the system is , but it is very important to me that i am able to read and write in the phone in all three languages which are Arabic , English and Chinese .
 I don't know if it is possible to be able to view documents in these three languages and be able to write text in them in windows mobile phones simultaniously , i've heard about those localization programmes , but was wondering , if i for example use the Ce-Star  and install enable it to recognize chinese , will i lose the english .. and how about the arabic ???? i need to know very urgently , so please ..
.. will someone kindly please advise me on this matter .. and much thanks in advance!
