512MB of RAM means that the iPhone 4 likely won't repeat the missteps of the iPad

When Steve Jobs announced the iPhone 4 a few weeks ago, the company was happy to tout such features as its high-resolution Retina display, thinner body, FaceTime chat, 3-axis gyroscope, and increased battery life. However, Jobs left out some other important details that tech heads want to know like the clock speed of the A4 processor and the amount of RAM onboard.

Today, we have an answer to at least one of those questions. Mac Rumors is confirming that the iPhone 4 now has 512MB of RAM which is double what's included on the year-old iPhone 3GS and the recently introduced iPad. The increased RAM is likely to be welcome news for potential customers due to a problem that numerous iPad users have encountered with page caching issues in Mobile Safari due to the iPad's 1024x768 screen coupled with just 256MB of RAM.

John Gruber of DaringFireball fame described the issue shortly after the launch of the iPad:

There’s one severe problem in Safari for iPad, though: memory crapping out. MobileSafari for iPhone has always allowed you to open up to eight pages at a time. It tries to keep them all truly open, in RAM, so that you can quickly switch between them. But when it runs out of memory it starts flushing some of the pages. It doesn’t forget the URLs for those pages, and, in recent versions, it saves a static thumbnail image of the rendered page, but when you switch back to those purged pages, MobileSafari must reload the page...

The iPad also has 256 MB of RAM. But, in my use, iPad’s Safari isn’t able to keep nearly as many pages open as I can on my 3GS. In fact, sometimes it seems I can only have one, and every page I switch to gets completely reloaded. This is more than just annoying — it can lead to data loss if you have unsubmitted form data sitting in an “open” iPad Safari page.

With 512MB of RAM onboard and a slightly lower resolution than the iPad – 640x960 – the iPhone 4 hopefully won't have the same page caching issues and could possibly even provide better performance.

512MB of RAM puts the iPhone 4 on par with powerhouse Android phones like the HTC EVO 4G.

I doubt it was intentionally designed to be poor, but there's just a LOT of effort that goes into making the first product in a series work well. Design specs are often locked in months in advance, and hunting for bugs takes up a LOT of time.

It's like trying to complain the first video game in a series sucks after the second one comes out because they left out important stuff. Trying to put everything into version 1 gets you a shitty product 9 times out of 10 because it's the jack of all trades and master of none.
