What are some differences between "GSM" and "CDMA"

- Some noticeable differences between these two systems is that GSM devices come with a SIM card slot, but CDMA devices do not. - This means CDMA phones are a handset-based standard, with a phone number linked to a particular device. - To upgrade to another phone, a person must contact the network carrier, de-activate the old device and activate the new one. - GSM devices have the phone number linked to the SIM card. To change devices, you take out the SIM card from the old device and place it into the new device.

What are some of the software requirements needed to install the synchronization on the PC or Mobile device?

- Some software requires a specific operating system and cannot run on any other operating system. (Ex: Android apps only run on Android operating system) - Hardware requirements - Be aware of any defaults, limitations, or data caps for the environment. These will determine what is synchronized
