How many Gigabytes of internal storage does a Samsung Blackjack phone have?

The simple answer is: None! The Samsung Blackjack and Blackjack II both have no Internal Storage, but instead have a MicroSD port. MicroSD cards measure 5 mm × 11 mm × 1 mm (about the size of a fingernail), and can hold anywhere from 64 MB to 16 GB in size. They are relatively cheap, and you can easily get one in any retail store that sells photo camera or computer products. This has several advantages: You can connect a reader to your computer (along your microSD card) and transfer data directly, and if your phone gets damaged you can easily move all your data.
