Should I delete messages on my iPhone?

I'm just curious if having messages that can read back to the date I bought my iphone will slow it down? I know they archive after a certain number of messages but do I need to delete the old messages?

Don't worry about that Bro, since its an iphone it will never slow down even its memory is fully occupied, but I think that you should delete the messages that you don't need because it unnecessarily occupies your phone's space.

No, I've had messages on my iPhone for 6 months and it's not slowed down in the slightest. It's because those messages only take up such a minute part of the memory it's not going to hinder your phone at all plus it also has such a fast processor that it won't be bogged down like if it was a smaller phone with a smaller memory and processor.

A 160 character text would take up 320 bytes. If your memory space is 256mb that would equate to 268, 435, 456 bytes. Standard SMS message is limited to a 160 characters so if you use the memory entirely for text messaging, it would store 1, 677, 721 messages.
