There are many places where one can get cell phone upgrades. Upgrades for cellphone software are usually available from an application on their phone. If one wishes to upgrade to a new phone they can do so from their phone provider.
Many are available at no cost to you, but you will have to contact your service provider for the correct information.

Yes you can. But I am not sure how many times each upgrades
Yes you can! Many Smartphones now come with that capability or allow you to download an application to do so. Talk to your mobile phone provider to see if your phone is GPS capable or arrange an upgrade.
"Mobile Upgrade" for many cell phone companies means that you're eligible to get a new phone at a reduced cost. For example, Verizon customers (and I'm sure this is basically how it works with every other provider) when they are eligible for an upgrade, they can get a new cell phone at the cost someone would pay if they started a NEW contract with the company (the website shows the various prices). However, for many providers, this also extends your contract for another two years so be careful and read the fine print!
