.... and I'm sure it's all 100% true and unbiased, that article. Apple
are a major source of FUD these days, along with stifling creativity:

ALL ONE LINE that URL, I'm too lazy for Tinyurl.

it's also a *huge* exaggeration and downright misleading.

"Frequent and unexpected crashes of the device, crashes and freezes of
built-in apps and third-party apps, and loss of data."

jailbreaking itself does not do that. only if the user installs buggy
software can that occur.

"Dropped calls, slow or unreliable data connections, and delayed or
inaccurate location data."

pure nonsense. the dropped calls are because at&t has shitty coverage
in a lot of places. plus the location data is via skyhook or gps,
totally unrelated to whether the phone is jailbroken.
*
"Services such as Visual Voicemail, YouTube, Weather, and Stocks have
been disrupted or no longer work on the device."

pure bullshit. they all work just fine, other than voicemail which is
not really surprising if the phone is activated on an unofficial
carrier.

"Additionally, third-party apps that use the Apple Push Notification
Service have had difficulty receiving notifications or received
notifications that were intended for a different hacked device."

only if they install the patch that uses the same key for everyone who
installs the patch (whose bright idea was that?) when properly set up,
push works just fine.

"Other push-based services such as MobileMe and Exchange have
experienced problems synchronizing data with their respective servers."

i'm sure there's someone out there who had problems but as a general
rule, more fud.

"Security compromises have been introduced by these modifications that
could allow hackers to steal personal information, damage the device,
attack the wireless network, or introduce malware or viruses."

stealing personal information is also possible with approved apps and
the rest is a bit of an exaggeration. how many iphone viruses are
there? other than the sms hack, which affects any iphone, not just
jailbroken ones, the answer is zero.
*
"The hacked software has caused an accelerated battery drain that
shortens the operation of an iPhone or iPod touch on a single battery
charge.*"

it has in certain circumstances, but not as a general rule.
*
"Some unauthorized modifications have caused damage to the iPhone OS
that is not repairable. This can result in the hacked iPhone or iPod
touch becoming permanently inoperable when a future Apple-supplied
iPhone OS update is installed."

that's just pure rubbish. you can always put the phone into dfu mode
and restore a stock firmware. i know of *zero* cases where jailbreaking
has physically damaged the phone. there are hardware mods that could
of course damage it, but that's entirely different.
