I can't see very well from the picture, but I believe that there is no "flap" so I'll say:

I was only able to sex my GBB at 2inches because the flap was so difficult to find when it was 2inches below.

Take a needle, run it down where that light colored patch is down the middle.
Is it a flap? If so, female.
If not, try again. The spermathecae/uterus externus can sometimes stick on to the exuvia really well.
Still no flap? Male.

If you take the same pic but from the other end, might be better. Also, do you notice any male characteristics on the T yet?

What kind of male characteristics would you be referring to?
I was wondering the same thing myelf. Until it matures it's not going to have any male characteristics, aside from looking male ventrally, but we all know that is never a surefire way to determine gender. If it was to have matured, we wouldn't be having this conversation (hopefully) as I assuming that the OP would be able to tell.

I second the advice Hobo gave you, it's possible (from what I can see in the pictures) that light colored patch *could* be a flap.

I assumed by simply posting the original question and the apparent size of the molt that this spider could be mature and that the owner is not at all familiar with sexing. Confirmed by the second question containing "What male characteristics"?" And unless the owner is familiar with re-moistening the exuvia (assuming it is dried by now) then may have a difficult time figuring it out. Hence why I mention another angle on the pic. OR maybe my noob is showing?

I could easily tell that it wasn't mature just by still being able to see the black striping on the abdomen. The abdomen changes to completely orange before it matures.

Mature? :) 7. molt, maybe 2,5 inch... far from maturing.

Okay, conclusion: i tryed to roll down the light colored part, when it was fress, but i cant, because its too small. So im waiting for the next molt. Thank you the answering!! : happysmile88, newspidermom, grayzone, Hobo, ImDeadly, 1hughjazzspider, Shell, catfishrod69,!

The moult is excellent, unfortunately the picture lets you down.
Is there any chance of getting a more focussed pic, perhaps take it outside where you'll get much better lighting.
I find GBB hard to sex in the early stages as their spermatheca is rather small.
It looks as if you can see the male gonopore, but they look a little too large, perhaps the black tick mark in the middle is not a gap but a loose hair? If so then perhaps the mound seen is the fused spermatheca. However, you should be looking for the uterus externus to aid in the sexing as hobo has suggested.
I'm inclined to suggest it may be female, but a clearer picture would give a better indication.

Did you try wetting the molt a bit, to make it more easy to work with? I've used just plain water, and I've also used a little mineral oil in the past, both work well. Wet it, let it sit for a bit and then use a pair of tongs/tweezers to help spread it out more easily without ripping it. I just had to do this a couple weeks ago, with a smallish molt, that wasn't very fresh anymore, they can be tough to manipulate but it can be done.

Edit* I misread, you did try when it was fresh. I stull suggest trying to manipulate with tongs, something smaller then your hands, it does help with the smaller molts.
