Error : Cannot Install Java Applications/games using pc suite

Like me you have also encountered problem while installing applications using pc suite saying the phone is being used or busy.
I haven't found any solution for this but I can advice you to get the application installed most of times.
As you connect your phone via pc suite / ovi suite synchronization starts. Its a background process and we don't notice it. We cannot install application during this period. Wait for this to get over. Synchronization details will be displayed on your phone screen when it is complete.

Also, if you have just switch on-ed your device wait for sometime. There are many background process going on mainly music library updating.

Error: Messages not showing contact names

After sim removal or sim change the inbox won't be showing the senders name even it is saved. This is a simple problem and is due to change in contact memory. After sim change the contact memory get changed to ' both phone and sim '. Change it to phone and you can solve this.
