How to free more RAM on your cellphone

Method 1
Flight mode
Put your phone in "Flight mode" with Psiloc System Tools. Install System Tools, open it and select "Flight mode". This way you can restart the phone without your SIM card so there will be no running phone tasks in the background. Now you can have up to 3,5 MB of free RAM!

Note: ironically enough, Flight mode doesn't work when Smart Launcher is installed, at least in my case.
But i've also heard several reports of people who have both apps running without any problems.

Method 2
Smart Launcher trick
Install Smart Launcher and open it. Go to Options, Settings and put Launcher ON.
Now plug in your charger and switch off your phone. Wait untill the battery meter appears and short press the Menu button (don't hold).
The menu should appear and now you can have 3,5 to 4,5 MB free RAM! (Hold Menu button to check RAM).

The trick is that with the charger plugged in, the phone must get a minimum software support for charging, even when
the phone is switched off. And somehow Smart Launcher has still got it's shortcut running and that's the Menu button. So when
you press the Menu button, you go directly to the Menu without any other phone tasks running in the background so
you trick the phone and you have more free RAM!
Note: when you unplug the charger, the phone will switch off.

Method 3
Use software : SMan and Stacker (for UIQ OS)
Install those softwares on your cellphone
Open SMan, marking the running aplications (except SMan), press "end task"
Open Stacker, press compact menu, then press memory

Method 4
Menu
Close your menu not by selecting the right selection key "exit", or pressing the menu key another time, they only hide the menu app but do not close it, to close it select the left selection key "option" and scroll down and select "exit"
So when you open an app needs more ram reopen menu and close it, it's useful when play low bit rate video in realplayer paradis.

How to protect your cellphone from viruses

Switch to Bluetooth hidden mode.

If your phone has Bluetooth capability, ensure that the Bluetooth capability is switched to “hidden” or “invisible” mode unless you specifically need it to be visible. This will help prevent other Bluetooth-enabled devices from finding your phone (unless you grant them the necessary permission) and will therefore help protect your phone from worms that spread using the Bluetooth wireless technology.

Exercise caution before opening attachments.

When accepting applications sent via Bluetooth, or opening MMS attachments, exercise caution, just as you would when opening an email attachment on your PC, because they may include harmful software. Ensure the application or attachment comes from a known source, and be wary of opening files that have unfamiliar text attached to them, even if they come from someone you know.

Only download content from a trusted source.

Trusted sources may include operator portals[2] and other well-known brands that offer adequate protection against viruses and other harmful software. Be aware though that, as with emails, malicious or fraudulent users may be able to fake the appearance of a trusted source.

Consider anti-virus software.

Some software is available to prevent phone viruses. You may wish to consider downloading this software.

Contact your phone manufacturer if concerned.

If you think you have a virus, call the phone manufacturer’s care line. They can assist you confirm if it is a virus, and help fix the problem.
