Need Help with upgrade phone

[JL33]

This is my first time post, if something not right, I apologize.
I want to upgrade my phone but don't know what I can get base on my plan I have right now.
Here is what I currently have

$40.00 Free & Clear Plan + $10 credit each month
1000 Anytime Minutes + 120 adjust mins each month
Unlimited Night & Weekend Minutes
Monthly charge for service plan $40.0
Plan add-ons
Sprint Unlimited Data PackIncluded
Sprint Casual DataIncluded
Unl Shared Night&Wknd Min 7pmIncluded
Courtesy Minute AdjustmentIncluded
Unlimited Mobile To Mobile MinIncluded
Unlimited Text MessagingIncluded

the plan I currently have is from promtion/perk, I probably wouldn't able to get anything more base on what I already have
I haven't upgrade my phone for very long time, (out of contract for several years already)
How can I get a good deal on the phone? the phone I want is Samsung Ace (because I can use it overseas)

I know this is an old plan that is no longer exist so I afraid I will loose everything once I upgrade. (I spoke to the rep and she told me this info)
I'm happy with the package I have [except no picturemail :)]
anyway can anyone guide me with this?
thank you in advance

Go to BestBuy and use your $150 upgrade credit there. You don't have to change your plan or any of your add-ons.

OR call sprint *2 for telesales or account rep or Radioshack.

BTW, I asked the same thing at http://www.sprintusers.com/forum/showthread.php?t=185714
