I think that the blackberry is better than the iphone, because it has bbm but the thing is an iphone is bigger and has apps that you can download . I think that the blackberry is better just because it has bbm .

the things that can stop hacking
: passwords
: privacy settings
: fire wall
: adding people

having a password on your facebook or something like that can help you from getting hacked because bad things can happen if you dont have a password .

privacy settings is also a good way to stop people you dont know looking at your settings and your wall about yourself , if you dont have you privacy setting to only your friends can see then strangers could see where you are and what your doing and your number and where you live .

fire wall is a safty internet thing that you download to help stop people hacking onto your computer
becasue if you dont have something like that on your laptop or ipad or what you are using people can look at everything on your laptop and steal you stuff .

adding people that you dont know can be a big thing and bad things can happen , adding people you dont know can let them know where you are and how old your are and where you live and your number and all the privacy things like that , people can get in touch with you that you dont know .


there are alot of things on the internet that can keep you safe if you think .

cost
the cost of 3g out side wifi is like 50 pound a month or so
it is more than what wifi in your house is
if it was me i would use the free wifi in your house because it is better and it will be cheaper



the speed
the speed between them both has a lot , the 3g is abit slow when you are walking around in places and the speed in the house is very quick because you are using your own wifi and only you can use it not everyone .



the coverage
 the coverage on 3g , you can get anywhere you want at any time but with wifi in your house you can only get a certain amount of steps and then your wifi will automatically turn of .
