enough.
In my opinion CELL PHONES are so much better.
how can i upgrade my boost mobile cell phones and how much is it?
Pretty much every electronic device today produces heat. Small electronic devices such as cell phones and game boys produce very little heat, so a cooling system isn't needed. TVs on the other hand, produce lots of heat due to high power demands. Adequate ventilation is needed so your TV doesn't blow itself up.
In fact, there are some cell phones for free! Multiple different kinds are avadible for free on the att website now. But when there are no cell phones for free, there can be cell phones for as low as $19.99.
Not so much that you could notice it. Temperature is just a measure of how fast particles are moving, so all things that move cause heat (positive or negative heat).

yes they did, but they were much bigger than they are now!
A cheap cell phone is a cell phone that doesn't cost very much...usually they are not as good as expensive cell phones, but sometimes they are, sometimes you get a good deal.

Yes, there were cell phones. They were larger than modern day phones and much boxier. However, in 1996 Motorola came out with the first "Clamshell" phone.
