AT&T Announces iPhone 3G Pricing and Tips to be iReady

Online Resources Available to Help Customers Prepare for Purchase

Variety of Attractive Plans Combine Voice and Unlimited Data

Dallas, Texas, July 1, 2008

AT&T Inc. (NYSE:T) today announced iPhone 3G pricing for new and existing
AT&T customers, several attractive voice and data plans, and tips on how to
be “iReady” when iPhone 3G goes on sale at AT&T retail stores at 8 a.m.
local time on Friday, July 11.

“We can’t wait to offer iPhone 3G to our customers, and we want to make
sure the buying process is as easy as possible,” said Ralph de la Vega,
president and CEO of AT&T’s wireless unit. “Considering all the great new
features of iPhone 3G, we think our pricing and monthly plans present a
tremendous value for consumers and businesses alike.”

Pricing and Eligibility

AT&T is making it easy for customers to prepare for their iPhone 3G
purchase by posting “Get iReady” tips and frequently asked questions at
www.att.com/iphone. The site also will include a link for customers to
check their upgrade eligibility and other wireless account information.
iPhone 3G will be available for $199 for the 8GB model and $299 for the
16GB model. These prices require two-year contracts and are available to
the following customers:

* iPhone customers who purchased before July 11

* Customers activating a new line with AT&T

* Current AT&T customers who are eligible, at the time of purchase, for an
upgrade discount

Existing AT&T customers who are not currently eligible for an upgrade
discount can purchase iPhone 3G for $399 for the 8GB model or $499 for the
16GB model. Both options require a new two-year service agreement. In the
future, AT&T will offer a no-contract-required option for $599 (8GB) or
$699 (16GB).

Current customers may also choose to wait until they become eligible for an
upgrade discount. Eligibility is generally determined by amount of time
remaining on a current contract and payment history.

Current AT&T customers who are upgrading to iPhone 3G will pay an $18
upgrade fee and new AT&T customers will pay the standard $36 activation fee.

Voice, Data and Text Messaging Plans

AT&T brings iPhone 3G customers the best coverage on the globe and the
largest mobile-to-mobile calling community with unlimited calling to AT&T’s

Business customers interested in iPhone 3G should contact an AT&T business
sales representative or review their account information online to
determine their eligibility for upgrade pricing. Corporate e-mail and other
business applications require the Enterprise Data Plan for iPhone, which is
$45 a month and bundled with an eligible voice plan. Small business

iPhone 2.0 Software

All iPhone customers will benefit from the iPhone 2.0 software, which will
be pre-loaded on all iPhone 3Gs and available as a free download for
current iPhone customers. The new software will include numerous
enhancements, such as business-class e-mail access via Microsoft Exchange
ActiveSync; the iPhone Software Development Kit (SDK), which allows a
business to easily create applications customized to its needs; and the App
Store, which offers a wide-range of applications — from games to business,
education to entertainment and productivity to social networking. For
example, AT&T has developed YELLOWPAGES.COM Mobile for iPhone, which takes
local mobile search to a new level by allowing users to discover businesses
and local events based on their popularity among other iPhone users, get
directions and access business reviews.
