Sprint and T-Mobile are delaying the rollout of the sSamsung Galaxy 4 smartphone saying that Samung is facing inventory problems. Sprint will not sell the phone in its store this Saturday as originally planned. The company will just start taking online orders Saturday. Sprint is selling the phone for $250 with a two-year contract.

T-Mobile also said customers will not be able to order the phone online Wednesday as scheduled. Online orders will begin Monday instead. T-Mobile is selling the phone for $150 down plus 24 payments of $20, or $630 total.

On the other hand, AT&T will start offering the smartphone on Saturday. It can also be purchased online now, but AT&T won't ship the phone until April 30. The phone goes for $200 with a two-year contract.

Verizon said it will begin taking pre-orders for the device Thursday. It is selling the phone for $250 with a two-year contract and there's a mail in rebate to get $50 off the device.

Samsung on Wednesday said some wireless carriers will not be getting the phones as scheduled because of "overwhelming" demand.

"We expected to meet demands in the coming weeks," Samsung said in a statement.
