Hi,

I have my SE Xperia (2.1)

From the start when i had my phone, i cant see any file manger/ app installer to install the .apk i downloaded from PC. how can i get "file manger/ app installer"? They say i have to download it to Android market but i cant connect to the market using wi-fi It always says cant establish reliable data connection to the server even i have a very strong wifi. and how i suppose to install he file manger since i dont have any application installer to use. can you help me on this one?

Ok, you will need a File Manager from the Market to install this apk, however the problem you are facing is most likely a software issue with the handset in which case you will need to run an update.

Xperia? arc - PC Companion - Downloads - Mobile phones - Support - Sony Ericsson

Simply choose the "Repair" option through the support zone tab of PC Companion and after this you should be able to use the market.
