I have made some alterations to your essay that you may want to consider.
I also suggest that you think of a way of linking your paragraphs. Instead of writing Invasion of privacy... to introduce your first paragraph, and Crime... to introduce the second, why not use something like 'On one hand, cellphones have many advantages. For example...' and 'On the other hand, cellphones have many disadvantages. Like...'.
As for other ideas for the essay itself, what about texting in school (that annoys the teachers), and text language (tht wld b gr8!) - I'm sure this also annoys the teachers and worries the parents that maybe their child will forget how to write correctly.
