Have you recently had a hankering to replace that old mobile phone with an iPhone 3G? Well, Best Buy has you covered.

This week, (2/22-2/28) Best Buy is offering up to $100 discounts on certain iPhone models, but you must be a Reward Zone member as of yesterday. No signing up just to get the discounts for you!

The discounts are valid for regular Reward Zone members and Premier Silver members. Regular members can save $50 on both iPhone models, bringing the price down to $149 for the 8 GB and $249 for the 16 GB.

Premier Silver members can save $100 on both iPhone models. That’s $99 for the 8 GB and only $199 for the 16 GB. Of course with all of these great savings customers must expect some fine print.

The offer is only available in-store. All purchases require in-store activation, a two-year contract and are limited to one iPhone per customer. The offer is only good for new iPhones as well, refurbished models are excluded. To put the icing on the cake, offers are not available in all stores and are not valid for “Early Upgrade” customers currently under contract with AT&T.

To sum it up, if you are looking to switch to the iPhone 3G and are a Best Buy Reward Zone member, you now have more options. Just make sure you read the fine print.
